If you are referring to your device set values, I guess it is not currently tested

No. There is a test for that (ex5cu).

I have a user that is getting a segv in MatSetValues with aijcusparse. I suspect there is memory corruption but I'm trying to cover all the bases.

I have added a cuda test to ksp/ex56 that works. I can do an MR for it if such a test does not exist.

See the discussions here https://gitlab.com/petsc/petsc/-/merge_requests/3411
I started cleaning up the code to prepare for testing but we never finished it https://gitlab.com/petsc/petsc/-/commits/stefanozampini/simplify-setvalues-device/

Is there a test with MatSetValues and CUDA?
